# IL2P

AI-generated

Improved Layer 2 Protocol, by Nino Carrillo KK4HEJ:
an on-air format for [AX.25](../ax25/index.html.md) frames
that replaces [HDLC](../hdlc/index.html.md) framing with a compact header,
scrambling and Reed-Solomon forward error correction.
Unlike [FX.25](../fx25/index.html.md) it isn’t backwards compatible,
so both ends need to support it.
